SPECIFICATION forming part of Letters Patent No. 557,006, dated March24, 1896.

A li ti m d December 2, 1895. Serial No. 570,801. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES E. MILLER, a citizen of the United States,and a resident of Canton, county of Stark, State of Ohio, have inventeda new and. useful Improvement in Land-Rollers, of which the following isa full, clear, and exact description, reference being had to theaccompanying drawings, making part of this specification.

My invention relates to improvements in land-rollers and it consists ofcertain features of construction and combination of parts here inafterdescribed, and particularly pointed out in the claims.

The object of my invention is to produce a combined roller andpulverizer having any desired number of sections, the heads thereofhaving retaining-flanges so formed as to hold in place either surface ofthe girder-iron bars constituting the rolling or pulverizing surface ofthe sections, the machine thereby be-' coming interchangeably either aland-roller or a land-pulverizer. I obtain this object by the mechanismillustrated in the accompanying drawings, in Which Figure 1 is a rearview of the machine, showing the bars so arranged in one section as toproduce a roller and in the other a pulverizer. Fig. 2 is an end view.Figs. 3, 8 and 9 are sectional views of the heads. Figs. 4, 5 and 10 aresectional views of the intermediate supporting-wheels. Figs. 6 and 7 aredetailed views of a portion of the rim of the head, showing the methodof retaining the bars in the head and the retaining-rod and clampingnut.

Similar letters refer to similar parts throughout the several views.

The shaft A, upon which the machine is built, carries the heads B B andthe intermediate supporting-wheels O. The ends of the shaft arejournaled in depending brackets, as I, bolted to the box D, to which areattached the tongue E and the spring-supported seat F.

The machine may consist of as many sections as may be desired, which areformed in the following manner: In the inner surface of the rim of thecircular heads B and cast G in position. Upon the rim of theintermediate or supporting wheel 0 and also cast integral therewith areT-shaped apertures 0, through which the girder-iron bars are passed.

If it is desired to adjust the bars so as to form a pulverizer, one ofthe heads B and the intermediate supporting -wheel O are slipped uponthe axle A and the head and supporting-wheel fastened thereto by meansof bolt d, passing through the hub and impinging against the axle. Thegirder-iron bars are then passed through the T-shaped apertures c in thewheel 0, the flange on the end thereof engaging with the circumferentialgrooves in the head B and the web with the radial slots thereof. Thesecond head B is then passed onto the axle engaging the bars, asheretofore described, and is in turn bolted to the axle. As a furtherprotection against longitudinal displacements, a rod H, having on oneend thereof a head and upon the other a thread to engage with theclamping-nut, is passed through the heads B B and the wheel 0 and theclamping-nut placed thereon, as is shown in Figs. 6 and 7.

In case it should be desired to arrange the bars so as to produce aland-roller and thus present a greater surface to the ground theoperation is repeated, as heretofore described, with the exception thatthe bars are so adjusted in the heads that the flange or wider portionthereof shall be outermost and the narrower flange on the web shallengage the circumferential groove in the head. The same resultmay beaccomplished by the use of T-iron, and when employed the heads have castintegral therewith and on the inner side thereof radial slots andintersecting crossgrooves, as shown in Figs. 8 and 9, while theintermediate supporting-wheels have either circular apertures passingtherethrough, as shown in Fig. 4, or square apertures provided withintersecting radial apertures, as is shown in Fig. 5.

Having thus fully described my invention, what I desire to secure byLetters Patent is as follows: I

1. In a land-roller, the combinationof the axle j ournaled in thebrackets supporting the box carrying the tongue and seat, with the headsprovided with circumferential slots and radial grooves in the innersurface thereof, adapted to engage with girder-iron bars, substantiallyas and for the purpose set forth.

2. In a land-roller, the combination of the axle journaled in bracketssupporting the box carrying the tongue and seat, with the heads andintermediate supporting-Wheel O, adapted to interchangeably engage withthe flange and Web, of girder-iron bars, substantially as described andfor the purpose set forth.

3. The combination in a land-roller, of the axle journaled in bracketssupporting the box carrying the tongue and seat, with the heads havingon the inner surface thereof, annular grooves and radial slots, adaptedto interchangeably engage the web and flange of girder-iron bars,substantially as and for the purpose set forth.

4:. The combination in a land-roller, of the axle journaled in bracketssupporting the box carrying the tongue and seat, of the heads having onthe inner surface thereof, radial slots intersected by circumferentialgrooves,

and adapted to engage interchangeably the flange and Web of T-iron bars,substantially as and for the purpose set forth.

5. The combination in a land-roller, of the axle jonrnaled in bracketssupporting the box carrying the tongue and seat, of heads adapted toengage interchangeably With either the flanges or Web of T-iron barsthereby producing either a land roller or pulverizer, substantially asdescribed and for the purpose set forth.

6. In a land-roller, the combination with heads having annular groovesintersected by radial slots, of slats having crushing working faces androlling Working faces, said slats adapted to be interchangeably engagedin said slots and grooves, substantially as set forth.

In testimony whereof I have hereunto set my hand this 31st day ofAugust, A. D. 1895.

CHARLES B. MILLER.
